Hydrurga valiplundersignum Back to modern leopard seal
The future leopard seal is similar to the leopard seal that exist nowadays; they are the possible evolution of leopard seal. This future animal is call “Hydrurga valiplundersignum”, “Vali”came from the Latin word validus which means strongest and “plunder” means predator and “signum” means seal this is the possible evolution of a leopard seal in order to survive in the future Arctic and earth.

Future habitat:
The habitat of “Hydrurga valiplundersignum” is very similar to the Modern leopard seal that exists nowadays. They still can be seen in the area exist now, they will still be living in the area of the Arctic ,coasts of Antarctica, Southern coast of Australia (near Tasmania), Pacific oceans, Atlantic Ocean but not all can be on sub Antarctic islands because some of the sub-Antarctic island will disappear, They live is the southern part of the earth. Global warming cause the extinction mainly, they peninsula of the Antarctic will disappear since it is warming up ten times more than others and the rising of sea level. Refer to the blue shaded part of the diagram.
The “Hydrurga valiplundersignum” will spend more time in water than coast, since the Antarctica is made of 98% of ice sheet and global warming causes flow rate of glaciers to speed up since the ice shelves in the Antarctica start to melt and break down, in a period of time which is in the future when the “Hydrurga valiplundersignum” exist, the glacier will be melted so the sea level rises. This causes parts of Antarctica to disappear and the leopard seal will need to spend more time under water.
This is a diagram of the modern leopard seal used to live or being seen and the future animal Hydrurga valiplundersignum going to live. The red shaded area is where the modern leopard seal is currently living and the pink shaded area is where the Hydrurga valiplundersignum is going to live.

The black part will eventually start to disappear however not totally disappear like it is fully covered by the rising of sea level. Some land will be seen and partially will be covered up.
Structural adaptation 1:
The future animal of leopard seal’s is totally different to the modern leopard seal. The tail of the future animal is similar to the tail of crocodile; it allows the Hydrurga valiplundersignum to steer through water and also to protect them.
This helps the animal by swim faster by helping Hydrurga valiplundersignum to steer through water. Not only swimming faster but help them to protect themselves from predator. By wagging the tail with spikes.
The environmental pressure that given rise to this adaptation is that, global warming is affecting the arctic badly, from time to time parts ice shelves will break down , glaciers will melt down, and leopard seal will need to transform to be a better swimmer Hydrurga valiplundersignum. Because they will need to stay most of the time under water than on land or ice packs.
Structural adaptation 2:
Hydrurga valiplundersignum will have four flippers, unlike the modern leopard seal. However the four flippers are not exactly flippers.
They are like flatten webbed claws and they are as flat as flippers but also strong , since they have strong muscles at the top part of the joint part. The flatten webbed claws is streamlined.
This flatten webbed sharp claws help the animal by allowing the animal to protect themselves from their only predator Killer whales , swim faster and can travel steadier on ice. The claws allow the animal to protect themselves from killer whale since the killer whales hunt the leopard seal by Wave hunting, they will spy hop to see the prey that are resting on ice floe, which is the leopard seal the killer whales than gather in the groups around the prey and make waves that washes the prey down to the water, then other killer whale will start eating it and with this claw, Hydrurga valiplundersignum can use the claw to hand on to the ice floe. The claw help the Hydrurga valiplundersignum to swim faster since it is streamlined and the claws are also webbed.
The environmental pressure is that given rise to this adaptation is that killer whales is at the top of the food chain and killer whales are the only predator of leopard seals, and many leopard seals have been killed by killer whales and the rise of sea level and break down of ice shelves and the melting of ice and glaciers lead the Hydrurga valiplundersignum need to stay more under water.
Behavioral adaptation 1:
The Hydrurga valiplundersignum behave similar to modern leopard seals, they also gets together when it is time to mate during the Antarctic summer is that the Hydrurga valiplundersignum is not solitary like the modern leopard seals.
This helps the animal by hunting easier since there is team work just like what the killer whales do. This will help to hunt better since the prey can’t go anywhere if they are surrounded with predator.
The environmental pressure that given rise to this adaptation is that foods are declining, krill are lessening in numbers and penguins are threatened due to global warming. Krill are decreasing because krills’ food sources are the algae under the sea ice however the temperature have raised due to the global warming. And the penguin‘s food sources are krills and fishes, also the penguin can’t adapt to high temperature.
Behavioral adaptation 2:
The Hydrurga valiplundersignum are no longer solitary like the modern leopard seal, they will hunt together The Hydrurga valiplundersignum also hunt similarly to the modern leopard seal, bite on the prey and shake until the prey is totally dead however there are more ways now for Hydrurga valiplundersignum to hunt. They usually swims around and when there is prey they will attack them with it’s front flatten flipper like sharp claws if it is small but if it’s big they will wag the prey with its tail or bites the prey with its large mouth (the Hydrurga valiplundersignum have venom that kills prey).
This helps the animal by hunting more food and also hunting bigger preys like whales to achieve to be the top of the food chain , the Hydrurga valiplundersignum are no solitary ,so they can hunt together like the killer whales in the time of when the modern leopard seal exist.
The environmental pressure that might give rise to this adaptation is that the modern leopard is easily eaten by big predators and with the rise to this adaptation, the Hydrurga valiplundersignum no longer need to worry about killer whales their only predator of the leopard seal.
Physiological adaptation:
The Hydrurga valiplundersignum have special glands to produce venom, once the leopard seal bite on a prey the venom will make the prey dizzy. This can be used for big predator like the whale to make it dizzy or kill small preys like penguin
This helps the animal by helping the animal to catch preys that are large in size and unable to beat by a leopard seal and by this a leopard seal can catch prey easier.
The environmental pressure that might given rise to this adaptation is that leopard seals are the second of the food chain of the arctic and the killer whale are their only predator and in order to defend themselves they need to beat the killer whale.
